How to Add Text in After Effects
There is two main style of text in after effects.
1. Point Text: Point text is designed for situations where you only need to enter a word or phrase.
2. Paragraph Text: Paragraph text is tailored for more extended passages.
Here we explain to you how to create text layer using both styles in after effect:
Point Text 1. First, open the current After Effects project and to create a new text layer select "Layer" > "New" > "Text". 
You should see a Horizontal Type marker in the centre of the composition panel.
2. Start typing text and press enter if you want to move to a new line. 
You can also press Ctrl+V to paste in text from other sources.

3. When you set the text, press Ctrl+Enter to exit text-editing mode or choose another tool from the toolbar.
Paragraph Text 1. Open the after effect project and select the Horizontal type or Vertical Type tool depending on how you want the text to look. 
After that click and drag on the composition to create a bounding box for text.
2. Start typing in bounding box to enter new text and press enter to start a new paragraph. 
If you press Shift+Enter, then you will start a new line without the paragraph section.

When you have too much text content for the bounding box dimensions, you will see an overflow icon on the box.
3. Press Ctrl+Enter or click on another After Effects tool to leave text-editing mode.
